CVE-2025-3339: Online Restaurant Management System SQLi

CVE-2025-3339 Overview

A SQL Injection vulnerability has been identified in codeprojects Online Restaurant Management System version 1.0. The vulnerability exists in the /admin/user_update.php file, where improper handling of the ID parameter allows attackers to inject malicious SQL queries. This flaw enables remote attackers to manipulate database queries without authentication, potentially leading to unauthorized data access, modification, or deletion.

Critical Impact

This SQL Injection vulnerability allows unauthenticated remote attackers to execute arbitrary SQL commands against the database, potentially compromising sensitive customer and business data stored in the restaurant management system.

Technical Details for CVE-2025-3339

Vulnerability Analysis

This vulnerability is classified as a SQL Injection (CWE-89) with a secondary classification of Injection (CWE-74). The root issue lies in the improper neutralization of special elements used in SQL commands within the /admin/user_update.php file. When the application processes the ID parameter, it fails to properly sanitize or parameterize user input before incorporating it into SQL queries, allowing attackers to break out of the intended query structure.

The vulnerability can be exploited remotely over the network without requiring any authentication or user interaction. An attacker can craft malicious requests containing SQL injection payloads in the ID parameter to extract sensitive information from the database, modify existing records, or potentially gain further access to the underlying system.

Root Cause

The root cause of this vulnerability is the lack of proper input validation and parameterized queries in the /admin/user_update.php file. The application directly concatenates user-supplied input from the ID parameter into SQL queries without sanitization, allowing malicious SQL code to be executed by the database engine. This is a common vulnerability pattern in web applications that fail to implement prepared statements or proper input filtering.

Attack Vector

The attack is network-based and can be executed remotely without requiring authentication. An attacker can target the vulnerable endpoint by sending crafted HTTP requests to /admin/user_update.php with malicious SQL payloads embedded in the ID parameter. The exploit has been publicly disclosed, increasing the risk of exploitation in the wild.

The injection point in the ID parameter allows attackers to modify the intended SQL query logic. By injecting SQL meta-characters and additional query statements, an attacker can perform various malicious actions including extracting database contents, bypassing authentication mechanisms, modifying or deleting data, and potentially escalating to further system compromise depending on database configuration and permissions.

Detection Methods for CVE-2025-3339

Indicators of Compromise

• Unusual or malformed HTTP requests targeting /admin/user_update.php with SQL keywords in the ID parameter
• Database query logs showing unexpected SQL syntax errors or union-based query patterns
• Web server access logs containing SQL injection payload patterns such as single quotes, UNION SELECT, OR 1=1, or encoded variants
• Unexpected database query execution times indicating time-based blind SQL injection attempts

Detection Strategies

• Deploy Web Application Firewall (WAF) rules to detect and block SQL injection patterns targeting the ID parameter
• Implement database activity monitoring to detect anomalous queries originating from the web application
• Configure intrusion detection systems (IDS) with signatures for common SQL injection attack patterns
• Monitor application logs for repeated requests to /admin/user_update.php with suspicious parameter values

Monitoring Recommendations

• Enable detailed logging for all requests to administrative endpoints including /admin/user_update.php
• Implement real-time alerting for database errors that may indicate injection attempts
• Review web server access logs regularly for reconnaissance or exploitation attempts
• Monitor database user permissions and query patterns for signs of unauthorized data access

How to Mitigate CVE-2025-3339

Immediate Actions Required

• Restrict access to the /admin/ directory to trusted IP addresses only until a patch is applied
• Implement input validation on the ID parameter to accept only numeric values
• Deploy a Web Application Firewall (WAF) with SQL injection protection rules
• Consider taking the affected application offline if it contains sensitive data and cannot be adequately protected

Patch Information

No official vendor patch has been released for this vulnerability at the time of publication. Organizations using Code-projects Online Restaurant Management System 1.0 should contact the vendor for remediation guidance or consider implementing the workarounds below. For additional technical details, refer to the GitHub CVE Issue Tracker and VulDB entry #303553.

Workarounds

• Implement prepared statements with parameterized queries in the /admin/user_update.php file to prevent SQL injection
• Apply strict input validation to ensure the ID parameter only accepts integer values
• Use a WAF to filter malicious requests targeting the vulnerable endpoint
• Restrict network access to administrative pages using firewall rules or .htaccess configurations
• Consider running the database with least-privilege permissions to limit the impact of successful exploitation

# Example .htaccess configuration to restrict admin access
<Directory "/path/to/app/admin">
    Order deny,allow
    Deny from all
    Allow from 192.168.1.0/24
    Allow from 10.0.0.0/8
</Directory>
